Hello,

What's wrong with the following code:

[fabio@localhost projects]$ cat poc.c ; gcc poc.c ; ./a.out
main()
{
         #define A 100
         #define B 100
         #define C 100
         #define D 100
         int i,j,k,l;
         double ****array;
         //srand( (unsigned) time(0x0));
         for(i=0;i< A; i++)
         {
                 array = malloc(A * sizeof(double));
         }
         for(i=0;i< B; i++)
         {
                 array[i]=malloc(B * sizeof(double));
         }
         for(i=0;i<C;i++)
         {
                 array[i][i]=malloc(C * sizeof(double));
         }
         for(i=0;i<D;i++)
         {
                 array[i][i][i]=malloc(D * sizeof(double));
         }

         for(i=0;i<A;i++)
                 for(j=0;j<B;j++)
                         for(k=0;k<C;k++)
                                 for(l=0;l<D;l++)
                                         array[i][j][k][l] = (double) 0;

}
